* <B>INTERFACE TO NETSCAPE COMMUNICATOR PLUGINS (NEW C++ API).</B>
*
* <P>This supersedes the old plugin API (npapi.h, npupp.h), and
* eliminates the need for glue files: npunix.c, npwin.cpp and npmac.cpp that
* get linked with the plugin. You will however need to link with the "backward
* adapter" (badapter.cpp) in order to allow your plugin to run in pre-5.0
* browsers.
*
* <P>See nsPlugin.idl for an overview of how this interface fits with the
* overall plugin architecture.

// Plugin Instance Interface
/**
* The nsIPluginInstance interface is the minimum interface plugin developers
* need to support in order to implement a plugin instance. The plugin manager
* may QueryInterface for more specific types, e.g. nsILiveConnectPluginInstance.
*
* (Corresponds to NPP object.)
*
* The old NPP_Destroy call has been factored into two plugin instance
* methods:
*
* Stop -- called when the plugin instance is to be stopped (e.g. by
* displaying another plugin manager window, causing the page containing
* the plugin to become removed from the display).
*
* Destroy -- called once, before the plugin instance peer is to be
* destroyed. This method is used to destroy the plugin instance.
